The format is [Keep a Changelog](https://keepachangelog.com/en/1.1.0/), and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html). +## [Unreleased] + +### Added + +- `GUEST_UNRESPONSIVE` and `GUEST_SERVER_DOWN`: a guest call that times out is followed by one probe of the machine, + which reads `/proc` and the server's port and never talks to OpenCode. A machine under a tenth of its memory or over + four load per CPU answers `GUEST_UNRESPONSIVE` with the free memory, the load and the three largest processes, and + its one next step is to tell the user; one with nothing on the OpenCode port answers `GUEST_SERVER_DOWN`, which the + next `boxd_job` fixes. A machine that looks well keeps `TIMEOUT`, with the facts, and a probe that does not answer, + or answers with a line that is not JSON, keeps the plain timeout. +- `boxd_job` says what the session last did: `lastText`, its newest assistant text, redacted and cut to 300 + characters; `lastActivityAt`; and `pending`, the prompts waiting in its inbox. A run that completed but says its + task did not happen, such as a push refused with 401, no longer reads like a finished one. +- `boxd_submit` answers `queued: true` when the session was still running, so the prompt waits in its inbox for that + run. The read is a report, not a gate: a server that cannot say which sessions run still takes the prompt. A message + of another kind than the one asked for is never read as the assistant's last words or a run's outcome. +- A machine that is down says why. `boxd_job`'s `asleep` answer and each work in status carry `asleepBy`: + `boxd_sleep`, with the `sleptAt` the ledger recorded, or `idle_or_cli` for the idle bound or the boxd CLI. The plugin + clears the record when it wakes or recreates the machine. A wake outside the plugin followed by a later idle + hibernation still reads `boxd_sleep` with the older time: the plugin cannot see that wake. + +- The skill covers many works from one Code Mode loop, where a guest's credentials come from and what a session should + do on a 401, and how to look at a slow guest with the boxd CLI. The README and the golden-image page say that a + short-lived token stops every guest once nothing renews it. + +- The boxd CLI that runs inside a boxd machine is refused. It takes `--vm ` where the laptop CLI takes the machine + as an argument, so the plugin's commands failed one by one and the awake bound ended as `AWAKE_UNBOUND`. Every tool now + reads `boxd --help` once and, when it carries both phrases the in-VM CLI's help uses, answers `BOXD_MISSING`, saying the plugin drives remote machines from the laptop's CLI, + before it changes anything. A CLI that cannot answer `--help` is not refused. + +### Fixed + +- `boxd_ensure` on an open work rewrote its ledger record from a short list of fields and dropped the rest: the files + moved in and out and the last run's outcome. A drop then refused an output that a harvest had already brought back, + and status lost a failed run. Ensure now keeps every field and clears only the create intent. +- `boxd_job` could report an earlier run's error, or none, for a failed run. The guest's message list is newest first, + and the helper walked it oldest first and stopped at the first idle message. It now asks for the newest idle message + only, so a credential failure after a completed run reports `GUEST_AUTH_FAILED` with its own error. +- A coded error's tool result kept only `error` and `next`, so a Code Mode program or a script never saw what happened. + It is now `{ error, message, next }`. A timeout names its step, such as the guest's `phase` on `oc-`, and a + `GUEST_FAILED` message carries the helper's error and detail, redacted, or the last line the machine wrote. +- `docs/scripting.md` said a plugin code arrives as the RPC error `failed`. It arrives as the method's output; only the + four RPC codes are errors. +- A machine that rebooted, for example after a resize, lost the guest helper with its `/tmp`, and every tool call failed + with `GUEST_FAILED` until OpenCode restarted. A call that gets no answer now lists `/tmp`, and only when the folder is + clearly gone copies the helper again and runs once more. A crash, or a boxd CLI that failed, keeps its own error and + is never run twice. +- The skill said `directory` moves the guest's folder and that `boxd_job` answers only busy, idle or missing. It now + says `directory` is the laptop folder, names every job state, and says what `proof` `fresh`, `stale` and `missing` + mean. + ## [0.0.0] - 2026-11-10 diff --git a/README.md b/README.md index 3f09291..b33b090 100644 --- a/README.md +++ b/README.md @@ -54,10 +54,15 @@ session you cannot get back. the current project. 2. `boxd_submit` with the task, and optionally `files: [{ from, to }]` to copy data in.
